Embodiment Construction

[0027] Among them, SiO 2 and B 2 o 3 The total content is preferably 20-85mol%; Li 2 O, Na 2 O and K 2 The total content of O is preferably 5-25mol%; Bi 2 o 3 , La 2 o 3 and Y 2 o 3 The total content is preferably 0-20%.

[0028] Production method of the present invention:

[0029] The first step: take the raw materials according to the molar percentage composition, add the raw materials into a quartz crucible or a ceramic crucible, and melt them at a temperature of 1200-1300 ° C to obtain glass liquid;

[0030] Step 2: Add the glass liquid into the platinum crucible, and use the optical glass melting method to melt, clarify and homogenize it to obtain uniform glass. The melting temperature can be 1380-1450°C, and the optimum melting temperature is 1420°C.

[0031] SiO 2 and B 2 o 3 As a glass network generator, its total content is 20-85mol%; SiO 2 and B 2 o 3 The content of less than 20mol% will cause crystallization of the glass and reduce the chem...

Abstract

Disclosed is a light amplified Erbium Ytterbium codoped multi-component oxide glass, comprising SiO2, Al2O3, Li2O, Yb2O3, Er2O3, B2O3, Na2O, K2O, CaO, BaO, ZnO, MgO, etc. The raw materials are added into a crucible for melting, then the obtained glass liquid is added into a platinum crucible for melting, clarifying and homogenizing by an optical glass fusion method. The invention solves the problems in the prior art of narrow gain bandwidth, low glass transition temperature, complicated preparing technology and so on. The Erbium Ytterbium codoped multi-component oxide optical glass fiber can provide transmission bandwidth of 60nm and more even gain spectrum, higher glass transition temperature, better chemical and heat stability, can satisfy the increased requirements of the current optical transmission network.

Description

technical field [0001] The invention relates to an erbium-ytterbium co-doped multi-component oxide optical glass for optical amplification and a preparation method thereof. The glass can be used for the third optical communication window, that is, the broadband optical amplifier glass in the 1.55-1.65 μm band. Background technique [0002] Erbium-doped fiber amplifier (EDFA) is widely used in the optical communication field to amplify optical signals in the 1550nm band, wherein the optical amplification medium is an optical fiber doped with erbium ions. However, with the increasing demand for communication services and the rapid increase of Internet information transmission capacity, the information transmission capacity of optical fiber backbone network and optical metropolitan area network is rapidly expanding. The current wavelength division multiplexing (WDM) communication system is difficult to adapt to this demand, Dense Wavelength Division Multiplexing (DWDM) communic...
